Study of LDR Characteristics Apparatus, Model – LDR – 10


 

Study  of   L.D.R   (Light  Dependent  Resistance)  Characteristic  Apparatus  has   been   designed   to  draw  the  characteristic   curve  between   Resistance  and  Light   Intensity  at  different  voltages.

THE  INSTRUMENT  COMPRISES  OF  THE  FOLLOWING  BUILT  IN  PARTS  :

  1. One  continuously  variable  dc  regulated  power  supplies  of  0-30, Volts.
  2. LDR  is   mounted  on  the  panel  connections  are  brought  out  on   sockets.
  3. Voltmeter   and  current  meter  are  mounted  on  panel  to  measure  the  voltage  and current.
  4. Weight : 2.5 Kg Approximately
  5. Dimension : 210mm × 280mm × 82mm

EXPERIMENTS  :

  • To  plot  a  graph,  current  vs.  Intensity of  Light  at different  value of  voltage.

OTHER  APPARATUS  REQUIRED  :

  • Lamp  Holder  with  60  Watt  bulb.

 

Note: There may be any change in specification due to continuous R & D without notice.
